ADJUSTABLE RIVETING-STAKE.

To all whom 'it may concern:

Be it known that we, OLIVER SIEGLER, OTTO SIEGLER, and FERDINANDSTEGLER, citizens of the United States, and residents of Belleville,Illinois, have invented certain new and useful Improvements inAdjustable Riveting-Stakes, of which the following is a specification.

This invention relates to improvements in an adjustable riveting stakeand consists in the novel arrangement, construction and combination ofparts as will be fully hereinafter described and claimed.

The object of our invention is to construct a machine with a pluralityof riveting dollies adjustably mounted on a support for retaining rivetsin alinement and so adjusted as to correspond with the rivet openings inthe material to be riveted, each dolly being provided with a rivetholder whereby the rivet is held in position while the article to beriveted is placed in position.

A further object of our invention is to provide a mechanism in which therivets are inserted and by the manipulation of a handle the rivets areplaced in position and in alinement so that the article to be rivetedmay be placed on the machine, the holes in the article correspondingwith the position of the rivets so that the operator may readily andeasily rivet the article without the necessity of using a helper forsupporting one end of the rivet while the hammer is being brought incontact with the rivet.

provided with a projecting plate 12, its eenter being provided with anaperture through which a king bolt 13 is inserted. On the plate 12 ismounted a table 14, its center being provided with an aperture andrecess to accommodate the insertion of the head of the king bolt, thisconstruction permitting the table and the mechanism carried thereby tobe turned to accommodate the position of the workman.

On the table 14 is securely fastened a dolly-bar 15, its under surfaceon each side of the table provided with a T shaped groove 1G which isfor the purpose of accommodating the insertion of a bolt 17. By the bolt17, the guide frame 1S is held in position, one of said frames beinglocated on each side of the table and by the manipulation of the bolts,the supporting frames can be adjusted to accommodate the width of thearticle to be riveted. The dolly bar 15 is rigidly retained in positionupon the table 14 by bolting the same thereon or the same may be formedintegral with said table if found desirable. The upper surface of thedolly bar is provided with a curvilinear groove 19. In this groove reststhe periph` ery of each dolly 20, the connection at this point beingsuch as to permit the same to contact yet allow the dolly to be movedwhen desired to accommodate the use of the different styles of rivets.As we use rivets with different styled heads such as cone, flat or rounddepending on the material or article to be riveted and when such styledrivets are to be used, the dollies must be adjusted to bring the properrecesses in position to accommodate such rivet.

On each end of the dolly bar 15 is attached a support 21 in which ismounted a shaft 22, said shaft extending the entire length of themachine and passing through apertures formed in the center of eachdolly, thus retaining said dollies in alinement and on said shaft saiddollies may be adjusted laterally to accommodate the spacing of therivets. On said shaft 22 are mounted rivet holders 23, which consist ofa yoke, the arms 2st of said yoke located on each side of the dolly, thefree ends of said arms provided with recesses 25 in which is firmlysecured a bar 26, this bar extending the entire length of the machine,connecting each rivet holder and by this bar the entire series of rivetholders can be simultaneously operated.

In the rivet holder is pivotally mounted a rivet prong 27 which is madepreferably of spring material, its curved end provided with a slot 28through which vthe shank of the rivet projects; the teeth 29 contactingwith the inner surface of the rivet head thereby holding said rivet inposition. VThe rivet 'prong' is attached lto a plate 30 which is providewith a pair of perforated ears 31 and through said ears and throughholes 32 formed in the rivet holder is placed a pin 33 by which therivet prong is pivotally retained in position, the 'teeth 29 of saidrivet prongs being held incontact with the peripheries of the dollies byan expansive spring 34. On one end "of the shaft v-22 is mounted `ahandle'35 on which is carried a sliding `tooth 36 designed to come incontact with the recess 37 vformed in the projection 38 of the support21. The sliding 'tooth 36 is operated by the spring actuated handle'39and byfmeans of the tooth 36 the entire series of rivet holders can beretained in an elevated position, as shown in Fig. 4, when the handle isoperated and the tooth con` tacting with the lowest 'recess in theprojection 38. On the front surface of the dollybar 'is-placed aplurality of adjusting blocks 40 corresponding in Ynumber with thedollies, the said blocks provided with recesses 41 into "which the dollyprojects. The prongs 42 which project by the forming of therecess,'conta"ct with the sides of the dolly, retaining the same inposit-ion and by said prongs the dolly together with the rivet holdercan be'adjusted on the shaft 22.

The'adjusting-blocks 40 are'held in locked positionlafter adjusting bymeans of the-bolt 43; the head retained inea T shaped groove 44 formedin the dolly-bar; the threaded end of said bolt having a nut 45 which ismanipulated by the operator when desiring to adjust and work theadjusting blocks in position. The adjusting block is also providedwithfa dolly locking pin 46, said pin being spring actuated and providedwith a head 47 the inner surface ofthe head provided with a lug 48 whichis designed to come in contact with the projection 49 formed on the faceof the adjusting block, holdingthe pin out of contact with the dollywhen it is desired to rotate the'dolly when setting the same toaccommodate the required style of rivet.

The peripheries of the several dollies are provided with recesses, twoof said recesses shaped to accommodate the insertion of the end of thepin 46; a recess 50 formed to accommodate a cone-head rivet, the surfacebeing inclined so as to permit the cone-head rivets to be conveyed intothe recess 51 in which the rivets are held in perpendicular position inalinement so that the article to beriveted can be readily placedin`position over the rivet shan'ks.

The-recess 52`is arranged-to accommodate a flat-head rivet, its surfacetapering to a flat-tened surface, 53 formed on the dolly on which is setthe head of said rivet and also held vin position when the dolly hasbeen Vproperly adjusted so that the flat surface 53 is brought at thetop of the machine. p

The guide frames 18 have a pair of lhorizontal projecting prongs 54,said prongs through which 'projects a pin 58 and on said pin 'betweenthe Vvears is a coil spring 59 which is so arranged as to keep `theupper end of said pin in raised position, yet the spring beingo'fsuchtension as'to Ipermit the pin 'to lower when the article to be rivetedvcomes in contact therewith. The purpose of said pin is to permit theedge of the article to be riveted to contact with the side thereof whichwhen vregulated will act as a `guide for the article to be riveted,permitting -the holes in the material to correspond with the line ofrivets supported on the-machine, and the reason kof the pins loweringwhen 'contacted by the article is that lin the event the article is of-suoh length that `theoutermost guide is necessary, the inner one willnot interfere as the weight of the 'article will depress the pins. Thebars 55 'are held in horizontal position by the spring `actuated pin (30fitting into the bore 61 formed in the ba'r, and'said pin 60 ismanipulated by means ofthe knob 62. This pin is held in position in theboss`63 located on one of the prongs ofthe bifurcation, and whenonly oneset of bars are vused the other pair are permitted to hang in verticalposition out of the way of the operator.

The guide blocks 56 are `'held in their Shorizontally adjusted positionsupon the bars 55 Y* bymeans of `rthe thumb-screw 64 carried by theblock. See F ig. 3.

The operation of'our `invention is as follows: The machine as shown inthe drawings, is set `for handling cone-head rivets. The rivets areplaced in the grooves 50 between lthe teeth 29 of the rivet prong andwhen the entire series of rivet holders are provided vwith rivets, theoperator manipulates the handle'35 raisingthe rivet holders in aposition `as'shown-by solidlinesin fFig. 4and by dotted lines in Fig-5.The rivets areconveyed forward until the heads lodge within the'recesses 51. The article to be riveted is then placed on the guideframe, the edge contacting'with one ofthe guides as `set for thepurpose. rllhe punches or openings inthe material to beriveted beingin'alinement with the row of'rivets, the article is then vplacedover'therivet Shanks permitting thefshanks to project through the openings ;theoperator-then *manipulates the handle 35 bringing the same in horizontalplane as shown in Fig. 5, lowering the rivet holders, releasing theprongs from the rivet, the rivets being held in place upon the dolly bythe weight of the article and the rivets are then flattened by the useof a hammer and when completed the article is removed from the guideframes. When it is desired to use at-head rivets, the operatormanipulates the head 47 withdrawing the pin 46, then revolves the dollyto its proper position bringing the flat surface 53 on the top. The pin46 is then released and its end permitted to lodge within the recessformed in the dolly locking same. When it is desired t-o adjust thedolly horizontally on the shaft 22, the thumb-nut 45 is manipulated andthe entire mechanism is shifted on the shaft so as to regulate thespacing of the rivets and when adjusted the screw is tightened to retainthe mechanism in rigid position.

This construct-ion of mechanism has been especially designed forriveting stove and range bodies, and by its use the rivet heads are keptin perfect condition and unbattered. It disposes with the use of ahelper to hold the rivet-head while the shank is being flattened. By themovement or rotation of the individual dollies, we can assort the rivetsin the riveting alinement, bringing a mixture of flat or cone headrivets.
